Hi I am totally new to R and I would like to know how to perform both row and column normalization (so that both rows and columns sum to zero and have standard deviation of 1) using R on gene expression data. Thanks for the help. -- View this message in context: http://r.789695.n4.nabble.com/Row-and-column-normalization-tp3560257p3560257.html Sent from the R help mailing list archive at Nabble.com.
